Fiber reactive dyes which contain a sulfonamido-triazinyl group and one or two groups or the vinyl sulfone series

ABSTRACT

There are described water-soluble fiber-reactive dye-stuffs which possess a triazinylamino radical to which is bonded as second substituent an amino group or an N-containing heterocyclic group which, bonded via an arylene, alkylene or aralkyl radical, possesses a fiber-reactive grouping of the vinyl sulfone series, and to which is bonded as third substituent a sulfonamide group, wherein the sulfone radical is substituted by optionally substituted aryl, alkylenearyl or arylenealkyl or optionally substituted amino groups. 
     The dyestuffs are used for dyeing hydroxy - and/or carboxamido-containing material, in particular fiber material, such as cellulose fibers, wool and synthetic polyamide.

The invention relates to the technical field of fiber-reactive dyestuffs.

Fiber-reactive dyestuffs which contain an s-triazine radical to which a fiber-reactive group from the vinyl sulfone series is bonded and in which the third substituent is an optionally substituted amino group are known from U.S. Pat. No. 4,740,592, European Patent Application Publication No. 0,377,166 and from the Japanese Patent Publication Sho-40-17113.

The practice of dyeing using reactive dyestuffs has recently led to increased requirements being imposed on the quality of the dyeings and the efficiency of the dyeing process. There consequently continues to be a need for novel reactive dyestuffs which have improved properties, not only in respect of the fastnesses, and in particular exhibit a high degree of fixing on the material to be dyed and yield strong dyeings. Furthermore, there is an increasing demand for dyestuffs which give high-quality discharge and resist prints.

In discharge printing, a discharge agent is printed onto a dyed web of material (the ground shade) in a desired pattern; the discharge agent destroys the dyestuff, provided the dyestuff is dischargeable, so that, on completion of the discharge process, a white pattern appears on the dyeing (white discharge). If the discharge print additionally contains a discharge-stable dyestuff, then, after the discharge process has been completed and the customary treatment for fixing this admixed dye, a printed pattern is obtained on the ground shade in a different color (colored discharge).

In resist printing, the fabric is first printed with a suitable resist agent in a desired pattern. The fabric preprinted in this way is then cross-dyed (overpadded or overprinted) with a dyestuff which is capable of binding with the resist agent and therefore is no longer capable of becoming fixed to the fabric, with the consequence that no fixing of the dyestuff occurs on the resist-printed areas and the resulting dyeing (print) thus has a white pattern corresponding to the pattern of the resist agent.

The present invention furthermore relates to processes for the preparation of the dyestuffs of the general formula (1) according to the invention. They can be prepared in a manner which is customary per se by routes analogous to known synthesis routes specific for the particular class of dyestuff, by reacting the typical precursors for the particular dyestuff, at least one of which contains a group of the general formula (3), with one another, or by starting from a starting compound containing amino groups, of the general formula (60) ##STR7## in which F, R^(x) and n have the abovementioned meanings, and reacting this with a trihalogeno-s-triazine of the general formula (61) ##STR8## in which Hal is a halogen atom, such as, in particular, a chlorine or fluorine atom, with a sulfonamide of the general formula H-Q° where Q° has the abovementioned meaning, or an alkali metal salt thereof and with an amine of the general formula H-Q, where Q has the above-mentioned meaning, in stoichiometric amounts in any desired sequence, and if appropriate subsequently carrying out further necessary conversion reactions which are familiar to the expert.

In particular, the dyestuffs according to the invention can be prepared according to the invention by reacting a compound corresponding to the general formula (62) ##STR9## in which F, R^(x) and n have the abovementioned meanings and Hal is a halogen atom, such as, in particular, a chlorine or fluorine atom, with a compound H-Q° having the above-mentioned meaning or an alkali metal salt thereof, and reacting the resulting compound of the general formula (63) ##STR10## in which F, Q°, R^(z) and Hal have the abovementioned meanings, with an amine of the general formula H-Q, where Q has the abovementioned meaning,

or reacting a compound of the general formula (64) ##STR11## in which in which F, R^(x), Hal, Q and n have the abovementioned meanings, with a compound H-Q° having the abovementioned meaning or an alkali metal salt thereof, or reacting a compound of the general formula (60) with a compound of the general formula (65) ##STR12## where Hal, Q° and Q have the abovementioned meaning.

The reaction of a starting compound of the general formula (63) with the amine of the general formula H-Q is carried out in an aqueous or aqueous-organic medium in suspension or solution at a temperature between 30° and 100° C., preferably between 65° and 85° C., and at a pH between 3 and 7, preferably between 3.0 and 4. If the reaction is carried out in an aqueous-organic medium, the organic medium is, for example, acetone, dimethylformamide or N-methyl-pyrrolidone. The hydrogen halide liberated during the condensation is advantageously neutralized continuously by addition of aqueous alkali metal hydroxides, carbonates or bicarbonates.

The reaction of the compound of the formula (60) with the compound of the general formula (65) is preferably carried out at a temperature between 25° and 90° C., in particular between 45° and 75° C., and at a pH between 3 and 8, in particular between 3.5 and 6.5.

The reaction of a starting compound of the formula (62) with an amine of the formula H-Q is likewise effected in the same way as the reaction of the compound (63) with the amine H-Q in an aqueous or aqueous-organic medium in suspension or solution, although in this case a temperature between 15° and 70° C., preferably between 25° and 45° C., and a pH between 3 and 11.5, preferably between 3.5 and 7, is maintained.

Compounds of the general formula (63) are preparable not only by the reaction of a compound of the formula (62) with a compound H-Q° or an alkali metal salt thereof but also by reacting, analogously to known procedures, a compound of the formula (66) ##STR13## where Hal and Q° have the abovementioned meaning, with a starting compound of the formula (60), or, likewise analogously to known procedures, by reacting a precursor customary for the type of dye which, however, contains a group of the formula (67) ##STR14## where R^(x), Q° and Hal have the abovementioned meanings, with a further precursor optionally containing a group of the formula (67).

The amine of the formula H-Q is as a rule employed in the reactions in the form of a salt, such as a sulfate or preferably in the form of the hydrochloride.

The starting compounds of the formula (64) can be prepared by reacting, analogously to known procedures, for example a compound of the formula (62) with an amine of the formula H-Q where Q has the abovementioned meaning or a compound of the formula (68) ##STR15## where Hal and Q have the abovementioned meanings, with a starting compound of the formula (60). The starting compound (68) itself can in turn be prepared analogously to known procedures by reaction of a trihalo-s-triazine with an amine of the formula H-Q, where Q has the above-mentioned meaning.

The condensation of the halotriazine of the formula (61) with a compound of the formula H-Q is effected, likewise preferably in aqueous solution or suspension, at 0° to 30° C. at a pH between 1.8 and 9.5. Again the hydrogen halide set free in the course of the condensation is advantageously neutralized by continuous addition of aqueous alkali metal hydroxides, carbonates or bicarbonates.

Under certain reaction conditions a halotriazine radical may undergo hydrolysis; for this reason it is necessary that an intermediate or precursor which contains a protective group, such as, for example, an acetylamino group, should have the acetyl group eliminated from it by hydrolysis before the reaction takes place with the halotriazine. In which order the various abovementioned reactions between the halotriazine and amino starting compounds are conveniently carried out first will vary from case to case and depends in particular on the solubility of the amino compounds involved and on the basicity of the amino groups which shall react with the halogeno-triazine.

If diazo and coupling components of which one or both contain a group of the general formula (3) are used as starting substances in the azo dyestuff synthesis according to the invention, the reactions are carried out by the customary procedure of diazotization and coupling reactions, thus the diazotization is as a rule carried out at a temperature between -5° C. and +15° C. and at a pH below 2, by means of a strong acid and an alkali metal nitrite in a preferably aqueous medium, and the coupling reaction is as a rule carried out at a pH between 1.5 and 4.5, in the case of a coupling component which contains amino groups, and at a pH between 3 and 7.5, in the case of a coupling component which contains hydroxy groups, and at a temperature between 0° and 25° C., likewise preferably in an aqueous medium.

According to the invention, phthalocyanine dyestuffs according to the invention can also be prepared, for example, by using a phthalocyaninesulfonyl chloride or a phthalocyaninesulfonyl chloride containing sulfo groups as the starting substance and reacting this with an amine of the general formula H-Q, where Q has the above-mentioned meaning, and if appropriate with another amine, such as, for example, an amine of the general formula --NR² R³, where R² and R³ have the abovementioned meaning. Several such procedures for the reaction of phthalocyaninesulfonyl chlorides with amines are described in the literature, such as, for example, in U.S. Pat. No. 4,745,178 and the literature additionally cited in this respect therein.

The starting sulfonamides of the formula H-Q° are generally well-known and have been extensively described in the literature or can be prepared analogously to known procedures forming part of the general expertise of a chemist.

Numerous starting amines of the general formula H-Q are likewise described in the literature, thus, for example, in German Patents Nos. 887,505 and 965,902, in German Offenlegungsschriften Nos. 2,040,620 and 2,614,550 and in European Patent Application publications Nos. 0,107,614, 0,144,766, 0,159,292 and 0,278,904.

to

According to the invention, the dyestuffs according to the invention can also be prepared starting from one or more starting substances containing a β-hydroxyethylsulfonyl group, such as from an amine of the general formula H-Q, where Q has the abovementioned meaning, but with the difference that the group(s) of the formula --SO₂ --Y are β-hydroxyethylsulfonyl groups, by first preparing, analogously to the abovementioned procedures according to the invention, a starting compound which corresponds to the general formula (1) with the meaning given, but with the difference that the group(s) --SO₂ --Y are β-hydroxyethylsulfonyl groups, and converting the β-hydroxyethylsulfonyl groups in this compound into other groups --SO₂ --Y corresponding to the compound (1) according to the invention analogously to known procedures, thus, for example, into ester derivatives thereof, such as, for example, of polybasic inorganic acids or of aliphatic and aromatic carboxylic or sulfonic acids, thus, for example, into compounds in which Y is the β-chloroethyl, β-sulfatoethyl, β-phosphatoethyl, thiosulfatoethyl, acetoxyethyl or β-toluylsulfonyloxyethyl group. Examples of esterifying and acylating agents which are suitable for this are the corresponding inorganic or organic acids or anhydrides or halides or amides thereof, such as, for example, sulfuric acid, sulfuric acid containing sulfur trioxide, chlorosulfonic acid, sulfamic acid, phosphoric acid, polyphosphoric acid, phosphorus oxychloride, mixtures of phosphoric acid and phosphorus pentoxide, acetic anhydride, toluenesulfonyl chloride and thionyl chloride.

The sulfation is carried out, for example, by reaction with concentrated sulfuric acid at a temperature between 0° and 20° C. or by reaction with chlorosulfonic acid in a polar organic solvent, such as, for example, N-methylpyrrolidone, at a temperature between 10° and 80° C. The sulfation is preferably carried out by introduction of the starting dyestuff containing β-hydroxyethylsulfonyl groups into sulfuric acid monohydrate at a temperature between 5° and 15° C.

Those compounds in which Y is the vinyl group can be prepared from analogous ester derivatives thereof by means of alkali, thus in an aqueous medium at a pH of 10 to 12 and a temperature between 30° and 50° C. in the course of 10 to 20 minutes. The synthesis of, for example, β-(dialkylamino)-ethylsulfonyl and β-thiosulfatoethylsulfonyl derivatives is carried out by reaction of vinylsulfonyl compounds thereof with the corresponding dialkylamine or with an alkali metal salt of thiosulfuric acid, such as sodium thiosulfate. All of these procedures of conversion of one group ---SO₂ --Y into another are familiar to the expert in this fiber-reactive field and are described in numerous instances in the literature.

The dyestuffs of the formula (1) according to the invention are suitable for dyeing and printing the most diverse materials, such as silk, leather, wool, polyamide fibers and polyurethanes, and in particular all types of fiber materials containing cellulose. Examples of such fiber materials are the natural cellulose fibers, such as cotton, linen and hemp, as well as cellulose and regenerated cellulose. The dyestuffs of the formula (1) are also suitable for dyeing or printing fibers which contain hydroxyl groups and are contained in blended fabrics, for example mixtures of cotton with polyester fibers or polyamide fibers.

The dyestuffs according to the invention can be applied to the fiber and fixed on the fiber in various ways, in particular in the form of aqueous dyestuff solutions and printing pastes. They are suitable both for the exhaustion process and for dyeing by the pad-dyeing process, in which the goods are impregnated with aqueous dyestuff solutions, if appropriate containing salts, and the dyestuff is fixed, after an alkaline treatment or in the presence of alkali, if appropriate under the action of heat. The dyestuffs according to the invention are particularly suitable for the so-called cold pad-batch process, in which the dyestuff is applied to the padder together with the alkali and is then fixed by storage at room temperature for several hours. After fixing, the dyeings or prints are rinsed thoroughly with cold and hot water, if appropriate with addition of a dispersing agent which promotes diffusion of the non-fixed portions.

The present invention therefore also relates to the use of the compounds of the general formula (1) according to the invention for dyeing (including printing) these materials and to processes for dyeing (and printing) such materials by a procedure which is customary per se, in which a compound of the general formula (1) is employed as the coloring agent, by applying the compound of the general formula (1) to the material in an aqueous medium and fixing it on the material by means of heat or by means of an alkaline compound or by means of both.

If anthraquinone dyestuffs according to the invention have an inadequate solubility in the alkaline dye liquor, this deficiency can be overcome in the manner which is known from the literature by addition of dispersing agents or other non-coloring compounds, for example a naphthalenesulfonic acid-formaldehyde condensate or in particular anthraquinone-2-sulfonic acid.

The dyestuffs of the formula (1) are distinguished by a high reactivity, good fixing capacity and very good build-up capacity. They can therefore be employed by the exhaustion dyeing process at low dyeing temperatures and require only short steaming times in the pad-steam process. The degrees of fixing are high and the non-fixed portions can easily be washed out, the difference between the degree of exhaustion and the degree of fixing being remarkably small, i.e. the soaping loss is very low. The dyestuffs of the formula (1) are also particularly suitable for printing, above all on cotton, and similarly also for printing nitrogen containing fibers, for example wool or silk or blended fabrics which contain wool or silk.

The dyeings and prints produced on cellulose fiber materials with the dyestuffs according to the invention have a good depth of color and a high fiber-dyestuff bonding stability both in the acid and in the alkaline range, and furthermore good light-fastness and very good wet-fastness properties, such as fastnesses to washing, water, seawater, overdyeing and perspiration, as well as a good fastness to pleating, fastness to ironing and fastness to rubbing.

The following Examples serve to illustrate the invention. The parts are parts by weight and the percentage data are percentages by weight, unless noted otherwise. Parts by weight bear the same relationship to parts by volume as the kilogram to the liter.

The compounds described by way of their formula in these Examples are shown in the form of the free acids; they are in general prepared and isolated in the form of their alkali metal salts, such as lithium, sodium or potassium salts, and are used for dyeing in the form of their salts.

The starting compounds and components mentioned in the form of the free acid in the following Examples, in particular the Tabular Examples, can likewise be employed in the synthesis as such or in the form of their salts, preferably alkali metal salts.

The absorption maxima (λ_(max)) in the visible range quoted for the compounds according to the invention have been determined with the aid of alkali metal salts thereof in aqueous solution. In the Tabular Examples, the λ_(max) values are placed in parentheses where the color shade is stated; the wavelengths are stated in nm.

EXAMPLE 1

45.3 parts of 3-(2,-sulfo-4,-methoxy-phenylazo)-4-hydroxy-7-amino-naphthalene-2-sulfonic acid are reacted in aqueous solution with 19 parts of cyanuric chloride at a temperature of 0° to 5° C. and a pH of 4. 9.7 parts of methanesulfonamide are then added, the pH is brought to 11 by means of sodium hydroxide solution and the reaction is carried out at a temperature of 40° C. and at a pH between 10 and 11 for about four hours. The monochlorotriazine-azo compound thus prepared is reacted in the synthesis solution with 29.5 parts of 3-(β-sulfatoethylsulfonyl)-aniline at a pH of 4 and a temperature of 85° C. When this condensation reaction has ended, the dyestuff according to the invention formed, which, written in the form of the free acid, corresponds to the formula ##STR38## is isolated as the alkali metal salt (sodium salt) by evaporation under reduced pressure or by spray drying. It has very good fiber-reactive dyestuff properties and, when used by the processes customary for fiber-reactive dyestuffs, gives deep, brilliant scarlet red dyeings and prints having good fastness properties, of which the fastness to water and fastness to perspiration may be emphasized out in particular. It is particularly distinguished by a high degree of fixing both in the exhaustion process at temperatures between 40° and 80° C. and in the cold pad-batch dyeing process. In discharge printing, pure white patterns are obtained on the scarlet-red ground.

EXAMPLE 2

9.7 parts of methanesulfonamide are added to a finely divided suspension of 19 parts of cyanuric chloride in 200 parts of ice-water, the pH is then brought to 10 to 11 with sodium hydroxide solution and the reaction is brought to completion at 0° to 3° C. and at a pH of 11 in the course of one hour, with further stirring. The solution formed is then brought to a pH of 5 with aqueous hydrochloric acid; 24.3 parts of 4-hydroxy-7-methylaminonaphthalene-2-sulfonic acid are added and the condensation reaction is carried out at 20° C. and at a pH of 3 to 3.5 for 2 hours. The sulfuric acid suspension of the diazonium salt, prepared in the customary manner, of 28.8 parts of 2-aminonaphthalene-1,5-disulfonic acid is then added to the solution of the coupling component thus obtained and the coupling reaction is carried out at 10° to 20° C. and at a pH of 6 to 6.5. 29.5 parts of 3-(β-sulfatoethylsulfonyl)aniline are then added and the condensation reaction is carried out at 85° C., a pH of 3.5 to 4 being maintained.

The resulting fiber-reactive dyestuff, which, written in the form of the free acid, has the formula ##STR39## is isolated as an alkali metal salt (sodium salt), for example after clarification of the synthesis solution by means of kieselguhr and filtration, by evaporation of the filtrate under reduced pressure or by spray drying. The dyestuff according to the invention produces, by the application and fixing processes customary in the art for fiber-reactive dyestuffs, deep orange dyeings having good fastness properties, of which good fastness to water and overdyeing may be emphasized in particular, on the materials mentioned in the description, such as, in particular, cellulose fiber materials, for example cotton. It is furthermore distinguished by a high degree of fixing on cotton.

EXAMPLE 3

The resulting solution is adjusted to pH 4.5 with aqueous hydrochloric acid. 29.5 parts of 4-(β-sulfatoethylsulfonyl)aniline are added, and the condensation reaction is initially carried out for three hours at 20° C., then for about a further two hours at 40° C., and at a pH of 4 to 5. To this batch is then added a solution of 54.5 parts of 3-ureido-4-3',6',8'-trisulfonaphth-2'-yl)azoaniline, and the third condensation reaction is carried out at pH 3.5 and at 85° C. The dyestuff according to the invention formed is isolated as an alkali metal salt (predominantly the potassium salt) by salting out by means of potassium chloride. It has, written in the form of the free acid, the formula ##STR40## and dyes the materials mentioned in the description, such as, in particular, cellulose fiber materials, for example cotton, in deep, reddish-tinged yellow fast shades.

EXAMPLE 4

45.3 parts of 3-(2'-sulfo-4'-methoxy-phenyl-azo)4-hydroxy-7-amino-naphthalene-2-sulfonic acid are reacted in aqueous solution with 19 parts of cyanuric chloride at a temperature of 0° to 3° C. and at a pH of 3.5 to 4. When the condensation reaction has ended, 11 parts of ethanesulfonamide are added at a pH of 10 to 11, and the second condensation reaction is completed within this pH range at 40° C. during about three hours. Then 29.5 parts of 3-(β-sulfatoethylsulfonyl)aniline are added to this batch, and the third condensation reaction is carried out at a pH of 3 to 3.5 and a temperature of 85° C.

The azo dyestuff according to the invention obtained as an alkali metal salt (sodium salt) salted out with sodium chloride from the as-synthesized solution adjusted to pH 7 and isolated has written in the form of the free acid the formula ##STR41## It exhibits very good fiber-reactive dyestuff properties and dyes the materials mentioned in the description, such as, in particular, cellulose fiber materials, such as cotton, in deep, bright scarlet-red shades with a high degree of fixing.

EXAMPLE 5

The resulting solution is then adjusted to pH 4 with hydrochloric acid and mixed with a solution of 31.9 parts of 8-hydroxy-1-amino-3,6-disulfonic acid in 800 parts of water; the second condensation reaction is carried out at 20° C. and at a pH of 2.5 to 3.

The coupling component thus prepared is admixed in the as-synthesized solution with the conventionally prepared aqueous, hydrochloric acid solution of the diazonium salt of 51.1 parts of 2-amino-6-(β-sulfatoethylsulfonyl)-naphthalene-1-sulfonic acid, and the coupling reaction is carried out at 15° to 30° C. and at a pH of 6. Then a pH of 3 to 3.5 is set, 29.5 parts of 3-(β-sulfatoethylsulfonyl)aniline are added, and the third condensation reaction is carried out within this pH range and at 85° C.

After clarification of the synthesis solution at a pH of 5.5, the resulting dyestuff according to the invention is isolated as an alkali metal salt (sodium salt) by spray drying. It has, written in the form of the free acid, the formula ##STR42## and exhibits very good fiber-reactive dyestuff properties. When used by the application and fixing processes customary in the art for fiber-reactive dyestuffs, it produces, for example, deep, bluish-tinged red fast dyeings and prints at a high degree of fixing on cellulose fiber materials, such as cotton.

EXAMPLE 372

48.3 parts of 1-(4'-sulfophenyl)-3-carboxy-4-(5"-amino-2"-sulfo-phenylazo)-5-pyrazolone are reacted in aqueous solution with 19 parts of cyanuric chloride at 0° to 3° C. and at a pH of 3.5 to 4. 9.7 parts of methanesulfonamide are then added, the pH is brought to 11 by means of aqueous sodium hydroxide solution and the mixture is heated to 50° to 60° C. It is subsequently stirred at 50° to 60° C. for a further 90 to 120 minutes, the pH being kept between 10 and 11, and when the condensation reaction has ended aqueous hydrochloric acid is added until the pH reaches 5 29.5 parts of 3-(β-sulfatoethylsulfonyl)aniline are then added and the mixture is heated to 85° C. and further stirred until the condensation reaction is complete, a pH of 3.5 to 4 being maintained.

The azo dyestuff according to the invention formed is isolated in the form of its alkali metal salt (sodium salt) by evaporation of the synthesis solution under reduced pressure or by spray drying. It has, written in the form of the free acid, the formula ##STR44## and has very good fiber-reactive dyestuff properties. When used by the known techniques, it dyes the materials mentioned in the description, such as, in particular, cellulose fiber materials, in deep, yellow shades with good fastness properties.

It is furthermore distinguished by a very high fixing yield both for dyeing by the exhaustion process between 40° and 80° C. and for dyeing by the cold-pad batch dyeing process.

EXAMPLE 373

18.8 parts of 1,3-diaminobenzene-4-sulfonic acid are added to a suspension of 19 parts of cyanuric chloride in 200 parts of ice-water. The mixture is stirred first at 0° to 5° C. and at a pH of 2.5 for about two hours and then at 0° to 5° C. and at a pH of 4 for about 30 minutes. 16 parts of ethanesulfonamide are then added, the pH is brought to 11 by means of sodium hydroxide solution, the temperature is slowly increased to 50° to 60° C. and the mixture is further stirred for about another 1.5 hours, a pH of 10.5 and a temperature of 50° to 60° C. being maintained. The pH is then brought to 7 by means of aqueous hydrochloric acid, 20 parts by volume of an aqueous 5N sodium nitrite solution are added and diazotization is carried out by slowly adding this mixture to a mixture of 50 parts by volume of concentrated hydrochloric acid and 600 parts of ice. The mixture is subsequently stirred for about a further 2 hours and any excess of nitrous acid is destroyed in the customary manner by means of sulfamic acid.

The resulting diazonium salt suspension is then added to an aqueous solution of the sodium salt of 60 parts of 4-hydroxy-5-amino-6-[4'-(β-sulfatoethylsulfonyl)-phenylazo]-naphthalene-2,7-disulfonic acid. The coupling reaction is carried out at 15° to 25° C. and at a pH of 4.5 to 5.5, 29.5 parts of 4-(β-sulfatoethylsulfonyl)-aniline are then added and the condensation reaction is carried out at 85° C. and at a pH of 3.5 to 4 for about 2 hours. The mixture is subsequently clarified with a little kieselguhr at about 40° C. and filtered and the filtrate is evaporated.

A black powder, containing electrolyte, of the alkali metal salt (sodium salt) of the disazo compound of the formula ##STR45## is obtained. It has very good fiber-reactive dyestuff properties and dyes cotton, for example, in strong navy blue shades.

EXAMPLE 374

To prepare an azo dyestuff according to the invention, the procedure is in accordance with the procedure of Example 373, but instead of the 29.5 parts of 4-(β-sulfatoethylsulfonyl)-aniline in the reaction with the chlorotriazine compound, the same amount of 3-(β-sulfatoethylsulfonyl)-aniline is employed and instead of 11 parts of ethanesulfonamide 16 parts of benzenesulfonamide.

The alkali metal salt of the disazo compound of the formula ##STR46## which, for example, dyes cotton in strong navy blue shades, is obtained.

EXAMPLE 484

49 parts of 1-amino-2-sulfo-4-(3'-amino-4'-sulfo-phenyl)amino-9,10-anthraquinone are reacted in aqueous solution with 19 parts of cyanuric chloride at 0° to 5° C. and at a pH of 3.5 to 4. 9.7 parts of methanesulfonamide are then added, the pH is brought to 11 by means of aqueous sodium hydroxide solution and the temperature of the mixture is slowly increased to 50° to 60° C. The mixture is further stirred in this temperature range for some time, and when the condensation reaction has ended the pH is brought to 5 with aqueous hydrochloric acid, 29.5 parts of 3-(β-sulfatoethylsulfonyl)-aniline are added and the third condensation reaction is carried out at 85° C. and a pH of 3.5 to 4.

After customary clarification of the synthesis solution, the dyestuff according to the invention of the formula (written in the form of the free acid) ##STR58## is obtained as an alkali metal salt (sodium salt) by evaporation of the filtrate. It dyes the materials mentioned in the description, such as, in particular, cellulose fiber materials, for example cotton, in deep, brilliant blue shades by the application and fixing processes customary for fiber-reactive dyestuffs.

EXAMPLE 485

To prepare an anthraquinone dyestuff according to the invention, the procedure is in accordance with the procedure of Example 484, but instead of 3-(β-sulfatoethylsulfonyl)-aniline, the same amount of 4-(β-sulfatoethylsulfonyl)-aniline is employed. A blue dyestuff with equally good dyeing properties, which, for example, produces deep, brilliant blue dyeings and prints on cotton, is obtained.

EXAMPLE 486

To prepare an anthraquinone dyestuff according to the invention, the procedure is in accordance with the procedure of Example 484, but 49 parts of 1-amino-2-sulfo-4-(3'-amino-2',4',6'-trimethyl-5'-sulfo-phenyl)amino-9,10-anthraquinone are employed as the starting anthraquinone compound. The dyestuff has, written in the form of the free acid, the formula ##STR59## It exhibits very good fiber-reactive dyestuff properties and produces, for example, prints and dyeings in deep, brilliant blue shades also cotton by the application and fixing processes customary in the art.

EXAMPLE 487

A fine suspension of 19 parts of cyanuric chloride in 100 parts of ice-water is added to about 3,000 parts of an aqueous solution, having a pH of 7 and a temperature of 0° to 5° C., of 31.6 parts of the triphendioxazine compound of the formula ##STR60## The mixture is further stirred at 0° to 5° C. and at a pH of 6.5 to 7 for about another 1.5 hours, and when the condensation reaction has ended, a solution of 11 parts of ethanesulfonamide in 30 parts of water is added, the pH is brought to 11 by means of sodium hydroxide solution, the mixture is slowly heated to 50° to 60° C. and is further stirred at this temperature and this pH for about another two hours, 29.5 parts of 3-(β-sulfatoethylsulfonyl)aniline are then added and the third condensation reaction is carried out at a pH of 3.5 to 4 and a temperature of 80° to 90° C.

After the customary clarification of the synthesis solution, the anthraquinone dyestuff according to the invention is obtained from the filtrate--for example by spray drying--as an alkali metal salt (sodium salt). It has, written in the form of the free acid, the formula ##STR61## and produces deep, reddish-tinged blue dyeings and prints with good fastness properties by the application and fixing processes customary in the art for fiber-reactive dyestuffs.

EXAMPLE 501

A homogeneous mixture of 106.2 parts of the nickel phthalocyanine compound of the formula ##STR67## in 300 parts of ice and 600 parts of water is brought to a pH of 7 with sodium hydroxide solution. A fine suspension of 19 parts of cyanuric chloride in 200 parts of ice-water is added and the reaction is carried out at 0° to 5° C. and at a pH of 4.5. 9.7 parts of methanesulfonamide are then added, the pH is brought to 11 by means of sodium hydroxide solution, the mixture is slowly heated to 60° C. and stirred at 60° C. and at a pH of 10 to 11 for another two hours, and when this second condensation reaction has ended 29.5 parts of 3-(β-sulfatoethylsulfonyl)-aniline are added.

When used by the customary application and fixing processes, for example, deep, bluish-tinged green dyeings and prints with good fastness properties are obtained on cellulose fiber materials, such as cotton.

EXAMPLE 502

To prepare a copper phthalocyanine compound according to the invention, the procedure is in accordance with the procedure of Example 501, but instead of 3-(β-sulfatoethylsulfonyl)-aniline, the same amount of 4-(β-sulfatoethylsulfonyl)-aniline is employed. The dyestuff according to the invention exhibits the same good dyeing properties as that of Example 501 and likewise produces fast bluish green dyeings and prints.

EXAMPLE 503

a) An aqueous, neutral solution of the sodium salt of 32.0 parts of the hydrazone of 2-carboxy-5-sulfophenylhydrazine and benzaldehyde in about 160 parts of water is added together with stirring at 5° to 15° C. to a conventionally prepared aqueous solution of the diazonium salt of 24.6 parts of 6-acetylamino-4-sulfo-2-aminophenol, then 25.0 parts of copper sulfate pentahydrate are added, and a pH of 5 is maintained by means of sodium carbonate. The reaction batch is subsequently stirred at 15° to 25° C. until diazonium compound is no longer detectable.

b) In the copper complex formazan compound synthesized under a) the acetylamino group is hydrolyzed to an amino group directly in the as-synthesized solution at a temperature between 90 and 100° C. in the course of 5 to 10 hours following addition of 6 to 10 times the molar amount of concentrated aqueous sodium hydroxide solution (the acetylamino copper formazan compound can also be salted out beforehand from the as-synthesized solution by means of sodium chloride and isolated and then be hydrolyzed in about 3% strength aqueous sodium hydroxide solution). The amino-containing copper complex formazan compound obtained can be isolated by salting out with sodium chloride after the pH has been brought back down to a value of about 4.

c) The formazan compound obtained under b) is reacted with cyanuric chloride. Advantageously this is done by starting from a solution of b) at pH 4 by reacting the solution with 16.6 parts of cyanuric chloride in the course of 3 to 4 hours at a temperature of 0° to 5° C. and a pH between 3 and 4 maintained with aqueous sodium carbonate solution, with thorough stirring to form the 2,4-dichloro-s-triazin-6-ylamino copper complex formazan compound.

d) To the as-synthesized solution of c) is added an aqueous solution of 16 parts of benzenesulfonamide in about 100 parts of water, the mixture is heated to 40° to 50° C. and a pH of 9 to 10 is maintained by means of an aqueous sodium hydroxide solution until the reaction has ended after 3 to 4 hours. The as-synthesized solution obtained is then clarified at 40° to 50° C., and the synthesized monochlorotriazine compound, either after intermediate isolation from the filtrate by addition of sodium chloride or potassium chloride or directly in this solution, is reacted with 28 parts of 3-(β-sulfatoethylsulfonyl)aniline at a pH between 3 and 4 and at a temperature between 60° and 80° C. in the course of 5 to 10 hours to form the copper complex formazan compound according to the invention.

After clarification the compound of the invention is salted out from the filtrate by means of sodium chloride or potassium chloride or isolated by evaporating to dryness or spray drying. This produces the alkali metal salt (sodium or potassium salt) of the compound of the formula ##STR69## as a dark powder containing electrolyte salt. The compound according to the invention has very good dyestuff properties and dyes the materials mentioned in the description in blue shades having a weakly reddish tinge. Especially cellulose fiber materials, such as cotton, and regenerated cellulose fiber materials are dyed by the application and fixing methods customary in the art for fiber-reactive dyestuffs in dark shades, for example from an aqueous, long liquor at 40° to 80° C. in the presence of an acid-binding agent. Similarly, very high color yields are obtained in the cold pad-batch processes. Following customary aftertreatment, for example 10 minutes' soaping and rinsing with water, the dyeings obtained according to the invention are notable for very good light fastness properties in the dry state and also when moistened with tap water or an alkaline or acid perspiration solution and for good wet fastness properties, such as wash, chlorinated water, chlorine bleach, alkali, perspiration and peroxide fastness properties. Furthermore, they show good acid fading resistance, and the dyeings are readily dischargeable. Of particular note are the very high buildup capacity and the high rates of fixation in the exhaust and pad process.

EXAMPLE 504

a) 18.4 parts of cyanuric chloride are suspended with or without a nonionic auxiliary in a mixture of 50 parts of water and 50 parts of ice, then an aqueous solution of 16 parts of benzenesulfonamide in 100 parts of water is added while a temperature of 0° to 5° C. and a pH of 10 to 11 are maintained, and the batch is subsequently stirred until free cyanuric chloride is no longer detectable.

b) To the optionally clarified solution of the monocondensation product obtained according to a) is added an aqueous solution, prepared according to Example 503a to 503b and adjusted to pH 5, of the amino copper complex formazan compound, the batch is heated to 30° to 40° C. and maintained at that temperature at a pH of 5 to 7 by means of aqueous 10% strength sodium carbonate solution until the condensation reaction of the dichlorotriazinylamino compound with the amino group of the copper complex formazan compound has ended.

The monochlorotriazine compound obtained is identical to that of Example 503d and can be reacted analogously to the directions of the preceding example by further reaction with 3-(β-sulfatoethylsulfonyl)aniline to form the copper complex formazan compound of Example 503 according to the invention. The novel formazan compound thus obtained has similar dyestuff properties.

EXAMPLE 505

a) 18.4 parts of cyanuric chloride are suspended with or without a nonionic auxiliary in a mixture of 100 parts of water and 100 parts of ice, then 16 parts of benzenesulfonamide are added while a temperature of 0° to 5° C. and a pH of 10 to 11 are maintained, and the batch is subsequently stirred for about one hour until free cyanuric chloride is no longer detectable.

The batch is then adjusted to pH 6.

b) To the optionally clarified solution of the monocondensation product obtained according to a) is added a solution of 28 parts of 3-(β-sulfatoethylsulfonyl)aniline in 200 parts of water and the batch is heated to a temperature of 40° to 60° C. while pH 5 is maintained. Then an aqueous solution, prepared according to the preceding Example 503a to 503b and adjusted to pH 5, of the amino copper complex formazan compound is added and the pH is maintained at 3.5 to 5 for 4 hours.

The novel formazan compound thus obtained has similar dyestuff properties to the copper complex formazan compound obtained according to Example 503d.

EXAMPLE 506

To prepare a copper complex formazan compound according to the invention the procedure of Example 503 is followed, except that the hydrazone used in Example 503a is replaced with the equivalent amount of the hydrazone of 2-hydroxy-5-sulfophenylhydrazine and benzaldehyde.

This gives the alkali metal salt (sodium or potassium salt) of the compound of the formula ##STR70## as a dark powder containing electrolyte salt. The compound according to the invention likewise has very good fiber-reactive dyestuff properties and dyes the materials mentioned in the description, in particular cellulose fiber materials, in strong blue shades having good fastness properties.

EXAMPLE 571

a) 18.4 parts of cyanuric chloride are suspended with or without a nonionic auxiliary in a mixture of 100 parts of water and 100 parts of ice, then 16 parts of benzenesulfonamide are added while a temperature of 0° to 5° C. and a pH of 10 to 11 are maintained, and the batch is subsequently stirred for about one hour until free cyanuric chloride is no longer detectable.

The batch is then adjusted to pH 6.

b) To the optionally clarified solution of the monocondensation product obtained according to a) is added a solution of 28 parts of 3-(β-sulfatoethylsulfonyl)aniline in 200 parts of water and the batch is heated to a temperature of 40° to 60° C. while pH 5 is maintained. Then an aqueous solution, prepared according to the preceding Example 503a to 503b and adjusted to pH 5, of the amino copper complex formazan compound is added and the pH is maintained at 3.5 to 5 for 4 hours.

The novel formazan compound thus obtained has similar dyestuff properties to the copper complex formazan compound obtained according to Example 503d.

EXAMPLE 572

To prepare a copper complex formazan compound according to the invention the procedure of Example 503 is followed, except that the hydrazone used in Example 503a is replaced with the equivalent amount of the hydrazone of 2-hydroxy-5-sulfophenylhydrazine and benzaldehyde.

This gives the alkali metal salt (sodium or potassium salt) of the compound of the formula ##STR72## as a dark powder containing electrolyte salt.
